Abstract

In this paper we propose a non-local in-loop filter for video coding called Noise Suppression Filter (NSF). The filter is based on block matching procedure and performs video signal filtering in a transform domain. Filter parameters are derived from a reconstructed signal and do not require additional signaling. NSF can be applied to both luma and chroma components or for luma component only to decrease the complexity. Experimental results shows that the for random access configuration applying NSF for luma and chroma components provides 1.0%, 2.0% and 1.9% of BD-rate saving for Y, Cb and Cr components correspondently with 100% encoding time and 134% decoding time compared to VTM 1.0. For lumaonly NSF demonstrates 1.0% Y BD-rate saving with 100% encoding time and 123% decoding time.
